The primary focus of this thesis is to look at Scythai's historical, geographical and ethnologic background in order to understand Scythai's garment types and styles as described in Scythai-related documented records, previous studies and excavated artifacts. Based upon this, another objective lies in comparing and contrasting this information with ancient Korean garments to identify what kind of relationship exists between the two. The result from this study's objectives is summarized as follows. Firstly, ancient Korean and Scythai share similarities in art work, craftwork, accessories and the like, which allows us to make a guess at the relationship between ancient Korea and Scythai of that time. Secondly, Scythai garments are based on the tight and well-fitted Caftan Yugoje, which is tightly fit to the body, as well as including garments similar to the drapery Kiton and Tunic found in ancient Greek garments, from which can be seen that the garment of culture medium passing between the East and the West had nomadic horse-riders' ethnic characteristics and Eurasian characteristics. Thirdly, ancient Korean Scythai garments were found to have homogeneity in their garment culture in that northern nomadic cultural district's Hobok-Goseupje, i.e., open-front Caftan Jeogori and pants called Sangeuihago is its basic with a triangular cone hat shape (transformed hat) and boots, which is the basis for considering that ancient Korea exchanged culture with Scythai, who once lived as active northern nomads. However, it can also be seen that ancient Korea and Scythai garments differed in form depending on region, weather, culture, custom and the like. As such, Scythai and ancient Korea have an aesthetic bond because northern nomads and Scythai exchanged their cultural traits of the times. The evidence supports this idea as it seems that the characteristics of garments that can be considered to be Scythain in style are also commonly discovered in ancient Korean garments.

Purpose: This review article was written to investigate how the various factors, such as lacrimal thickness, CL's thickness and Dk, affects the influx of $O_2$ diffusion into the cornea. Methods: A mathematical model was proposed to analyze the oxygen diffusion reaching the cornea through the tear layers and contact lens based on Fick's law and the principle of continuity of the diffusion flux through the each layers. Results: The model predicts how the parameters such as the thickness of tear layer on the cornea, both the Dk and thickness of contact lenses etc., affect the oxygen tension at cornea and oxygen flux entering the cornea. Conclusions: It is found that either too flat or too tightly fitted contact lenses can cause the oxygen deficiency at/inside the periphery of the cornea because of the reduction of oxygen flux resulted from too thickened tear layer.

Presented in this paper was to evaluate and improve the usability of a web-based logistics information system. The system was developed for the domestic company to track and monitor its own transportation vehicles and for the customers to check the current location of their packages by using Global Positioning System (GPS) and Short Massage Service (SMS). Since the initial system was developed under a tight schedule set by the company, the system designers and programmers did not focus on the usability of the system but on the functionality. Consequently, some usability problems of the system were discovered during the heuristic usability evaluation. This study was required to solve these usability issues. Usability problems of the initial system were identified and analyzed, and the user's requirements for the system were re-evaluated to meet the company's expectation. Several alternative designs were developed by fitted guidelines and then a updated system was developed. The updated system had an empirical usability test to find how much the initial system was improved from the heuristic evaluation. Two kinds of data were gathered during the tests: objective (completion time and number of errors) and subjects' preference. Data showed the updated system is better than the initial system in terms of usability. Presented in this paper includes introduction of the Usability evaluation, usability engineering process applied in this research, alternative design of GUI, usability test and results.

To analyze recent changes in designer-specific garment composition, detail, and design elements of jackets, we classified jackets from the Paris Haute Couture Collection from 2000 S/S to 2019 F/W according to their designers and examined their characteristics. Our analysis of the jackets by Armani, Chanel, Dior, Jean-Paul Gaultier, and Valentino shows that the hour-glass silhouette was most common in Armani, Chanel, Dior, Jean-Paul Gaultier and Valentino jackets; Chanel used more straight silhouettes compared to other designers. Most jackets, regardless of the designer, had midlength waist-to-bottom, tight sleeves fitted to the body, natural shoulder shape, and solid color. Moreover, woven fabric was the most common material. Jackets with no collar were the most common for Armani, tailored collars for Dior and Jean-Paul Gaultier, and standing collars for Chanel and Valentino. For the closure method, Armani used hook-and-eye, Chanel, Jean-Paul Gaultier, Valentino used button closures, and Dior used snap closures the most. New design attempts by designers are bringing details and design elements together. In an era characterized by an abundance of designs and frequent replacement of each brand's creative designers, it is important to create and maintain a brand's unique design identity and philosophy that can meet consumers' elevated standards, which tend to be biased towards new and stimulating designs due to the development of the IT industry.

The purpose of this study was to analyze and compare the shapes, colors, patterns, and hairstyles of Qipao worn by heroines that were reconstructed over times, in a Chinese TV Drama set in the 1930s and televised in 1980 and remade in 2007. We investigated how the Qipao was reinterpreted. The results were as follows. First, in televised in 1980, Qipao borrowed the characteristics of Jing Pai Qipao, which became popular in Beijing. Jing Pai Qipao was characterized by a roomy and loose silhouette that does not expose a body line, Chinese traditional 5 colors, simple plain patterns and Chinese traditional flower patterns. For hairstyle, twist and permanent wave styles that were popular in the Republican Period were very common. On the other hand, in televised in 2007, Qipao was a Hai Pai style that was very popular in Shanghai in the 1930s. Hai Pai Qipao was characterized by a tight silhouette fitted to the body, various colors such as purple and beige other than the 5 colors, Western flower patterns and modern geometric patterns. Hairstyle was changed from bang hair to a permanent wave. Second, while had a modern reinterpretation of Jing Pai Qipao that was very popular in Beijing, rather than Hai Pai Qipao that became popular in Shanghai in the 1930s, used Hai Pai Qipao that was popular in Shanghai in the 1930s. In particular, demonstrated how the mass media should reinterpret past clothing by thoroughly studying and reflecting Shanghai Qipao in the 1930s and adding viewers' aesthetic taste of 2007 without damaging an original. Moreover, it confirmed that clothing can function as language and symbol within the mass media by connecting the color and pattern of Qipao with characters' traits and the plot. It suggests that was more advanced than filmed in the 1980s. The findings of this study might provide useful data to costume designers who reinterpret costumes from a new angle.

A mathematical model was proposed to analyze the vibration of diaphragm, such as the contact lenses fitted on the eyes, being subjected to the external sinusoidal pressure. The model incorporates the differential equations and their numerical solution program, based on the wave equations. Turbo-C and graphic software, formulated to describe the dependence of the various parameters involved in the vibration. The model predicts the radial distribution of amplitude, frequency dependence of both average displacement amplitude and the power of diaphragm whose edge is being either simply supported or rigidly clamped in vibration. The effect of variables such as thickness, radius, damping coefficients on the vibration characteristics was illustrated by the computer simulation of the derived program. As the frequency of driving pressure increases above the certain value determined by the boundary conditions and parameters the wave shape or pattern changes from simple arc to belly or loops having double antinode. It seems that the effect of outer antinode progressively increases as the frequency increases. If this kind of phenomena occurs to the contact lens on the cornea in vivo, it may cause an abnormal correction power in the lenses or pull off the eye due the increased rise of outer part of the lens.
